Particulates, basically charred carbon particles, visible by naked eyes are one of the many components in gases that pollute air. Did you know that? I hope you did. But did you know that they helped in process of raining as well? I hope you didn’t. Because in this post I am gonna tell each one of you exactly that. So these particulates go up in atmosphere and they get suspended after reaching a certain height. How they get suspended, you ask. Because as you go up the density of air decreases and at one point their weight is exactly balanced by the air surrounding it. Anyway, particulates help in the process of raining by acting as platforms for what is called nucleation. The vapors start condensing on these particulates and make a big enough drop that is heavy enough to drop. Anyway, that is not the end of story.

If we have a significant increase in the concentration of these particulates in atmosphere then fixed amount of water vapors will have many particulates to condense on and that can actually result in formation of small water droplets that wouldn’t be heavy enough to fall down. And they will just suspend there. And we won’t get rains. Interesting, no?

Harry: You know you just get to a certain point where you get tired of the whole thing.

Sally: What "whole thing"?

Harry: The whole life-of-a-single-guy thing. You meet someone, you have the safe lunch, you decide you like each other enough to move on to dinner. You go dancing, you do the white-man's over-bite, go back to her place, you have sex and the minute you're finished you know what goes through your mind? How long do I have to lie here and hold her before I can get up and go home. Is thirty seconds enough?

Sally: That's what you're thinking? Is that true?

Harry: Sure! All men think that. How long do you want to be held afterwards? All night, right? See there's your problem, somewhere between thirty seconds and all night is your problem.

Sally: I don't have a problem!

Harry: Yeah you do.

Harry: Would you like to have dinner?... Just friends.

Sally: I thought you didn't believe men and women could be friends.

Harry: When did I say that?

Sally: On the ride to New York.

Harry: No, no, no, no, I never said that... Yes, that's right, they can't be friends. Unless both of them are involved with other people, then they can... This is an amendment to the earlier rule. If the two people are in relationships, the pressure of possible involvement is lifted... That doesn't work either, because what happens then is, the person you're involved with can't understand why you need to be friends with the person you're just friends with. Like it means something is missing from the relationship and why do you have to go outside to get it? And when you say "No, no, no, no, it's not true, nothing is missing from the relationship," the person you're involved with then accuses you of being secretly attracted to the person you're just friends with, which you probably are. I mean, come on, who the hell are we kidding, let's face it. Which brings us back to the earlier rule before the amendment, which is men and women can't be friends.
